Racial disparities in Minnesota's criminal justice system are still prevalent, say researchers from the Council on Crime and Justice. On Wednesday, the council released a summary of the research it has compiled on the subject. Council officials say African Americans are 15 times more likely than whites to be arrested for low-level offenses. Assistant Minneapolis police chief Sharon Lubinski says the department has been working on measures to reduce incidents and perceptions of biased policing. Some of those policies began after the department collected racial traffic stop data a few years ago.
